Description

Technical Field

[0001] This utility model relates to the field of printing production technology, specifically to a die-cutting and leveling device for printing production. Background Technology

[0002] In the printing and packaging industry, die-cutting is a crucial post-printing process, primarily used to cut printed paper, cardboard, and other substrates into predetermined shapes (such as cartons, boxes, and labels). However, during die-cutting, the substrate may deform due to pressure from the cutting tool and uneven stress, resulting in curling, wrinkles, and other deformations. Without leveling, this directly affects the accuracy of subsequent folding, gluing, and other processes, and may even lead to the scrapping of the finished product. Therefore, leveling after die-cutting is an important step in ensuring the quality of printed materials.

[0003] Currently, most die-cutting and leveling devices for printing production on the market are equipped with a leveling machine body and a heated roller structure, which eliminates deformation by heating and softening the substrate and pressing it with rollers. However, in actual use, the die-cut printed materials directly enter the leveling machine, and are prone to lateral displacement and skew due to their own weight or fluctuations in conveying speed. This causes the material entering the heated roller to deviate in position, resulting in uneven leveling, edge damage, and other problems, affecting the leveling quality. Utility Model Content

[0004] The purpose of this utility model is to provide a die-cutting and leveling device for printing production, so as to solve the problem mentioned in the background art that conventional leveling machines lack effective support and limiting devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting and leveling device for printing production, comprising a leveling machine and a heating roller. A support plate and a pair of swing arms are rotatably mounted on the side wall of the leveling machine at a position corresponding to the heating roller. A fixing rod is fixedly mounted between the pair of swing arms. An elastic member connects the fixing rod to the leveling machine. A positioning rod is fixedly mounted at the end of each swing arm. Positioning grooves for accommodating the positioning rods are provided at both ends of the support plate, so that the positioning rods cooperate with the positioning grooves to provide stable support for the support plate.

[0006] Preferably, a pair of supports are fixedly installed on the side wall of the leveling machine, the swing arm is rotatably installed in the supports via a rotating shaft, a screw is slidably installed between the pair of swing arms, and a pair of limiting sleeves are threaded onto the screw.

[0007] Preferably, the side wall of the swing arm is provided with a sliding hole for accommodating the screw.

[0008] Preferably, a protective plate is fixedly installed on the side wall of the leveling machine, and the elastic component is a tension spring hooked on the protective plate, with the other end of the tension spring connected to the screw.

[0009] Preferably, the side of the swing arm is integrally formed with a protrusion that extends to contact the protective plate.

[0010] Preferably, the two ends of the tray are respectively provided with grooves that are adapted to the length of the positioning rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model integrates material support and limiting / guiding functions by setting a foldable tray on one side of the leveling machine, ensuring that the material enters the heating roller leveling area smoothly to improve leveling accuracy. When the machine is stopped and idle, the tray folds along the matching trajectory of the positioning rod and positioning groove to fit against the side wall of the leveling machine, greatly reducing the space occupancy rate. The structure is simple and easy to operate, improving the overall performance of the equipment while effectively controlling the equipment investment cost. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5This utility model provides a technical solution: a die-cutting and leveling device for printing production, including a leveling machine 1 and a heating roller 3. The leveling machine 1 is a special equipment for post-printing processing, mainly used to level die-cut printed materials (such as cartons, boxes, labels, etc.), eliminating curling and wrinkles caused by die-cutting stress, ensuring that the printed materials are flat and crisp, and meeting the precision requirements for subsequent processing or direct use. A support plate 4 and a pair of swing arms 7 are rotatably installed on the side wall of the leveling machine 1 at positions corresponding to the heating roller 3. A pair of supports 6 are fixedly installed on the side wall of the leveling machine 1, and the swing arms 7 are rotatably installed in the supports 6 via a rotating shaft.

[0021] A screw 9 is slidably mounted between a pair of swing arms 7. The side wall of each swing arm 7 has a sliding hole for accommodating the screw 9. One side of the sliding hole has a stopping point for accommodating the screw 9. The screw 9 can slide along the sliding hole to the preset stopping point and be temporarily positioned. The position of this stopping point is designed to avoid the folding trajectory of the pallet. A pair of limiting sleeves 10 are threaded onto the screw 9. The distance between the two limiting sleeves 10 can be adjusted by rotating the limiting sleeves 10 and moving them axially along the screw 9. This allows for adaptation to printed materials of different widths. The limiting sleeves 10 constrain the material on both sides, preventing material displacement or skewing during feeding or leveling, thus ensuring processing accuracy. A fixing rod 11 is fixedly installed between a pair of swing arms 7. An elastic component connects the fixing rod 11 to the leveling machine 1. A protective plate 2 is fixedly installed on the side wall of the leveling machine 1. The elastic component is a tension spring 12 hooked onto the protective plate 2. The other end of the tension spring 12 is connected to a screw 9. The tension spring 12 pulls the swing arms 7 toward the protective plate 2 through elastic tension, forming a continuous and buffered constraint force. A protrusion 13 is integrally formed on the side of the swing arm 7. The protrusion 13 extends to contact the protective plate 2. The protrusion 13 extends along the tangential direction of the swing arm 7 around the rotation direction of the side wall of the leveling machine 1, and the extended end always faces the protective plate 2. The purpose of this setting is to constrain the rotation of the swing arm 7 to a preset maximum angle. A positioning rod 8 is fixedly installed at the end of the swing arm 7. The two ends of the support plate 4 are respectively provided with positioning grooves 5 for accommodating the positioning rod 8, so that the positioning rod 8 cooperates with the positioning grooves 5 to provide stable support for the support plate 4. The two ends of the support plate 4 are respectively provided with grooves 14 that are adapted to the length of the positioning rod 8. The advantage of this setting is that it provides sufficient room for the positioning rod 8 to swing with the swing arm 7, avoids hard collision between the positioning rod 8 and the support plate 4 body during the swing, and further ensures the matching accuracy between the swing arm 7 and the support plate 4.

[0022] Before starting the equipment, adjust the key components according to the width of the printed materials to be processed (such as cartons, boxes, labels, etc.). The operator rotates a pair of limit sleeves 10 on the screw 9. By moving the limit sleeves 10 along the axial direction of the screw 9, the distance between the two limit sleeves 10 is adjusted to match the width of the printed materials to be processed, thus preparing for subsequent constraint of material position and prevention of displacement.

[0023] When the die-cut printed materials enter the leveling machine 1 for processing, the pallet 4 serves as a support platform, providing stable support for the printed materials. When the swing arm 7 is in the extended state, the positioning rod 8 fixed at its end is precisely accommodated in the positioning groove 5 at both ends of the pallet 4. Through the precise cooperation between the positioning rod 8 and the positioning groove 5, the pallet 4 is provided with stable support, ensuring that the pallet 4 always maintains a horizontal posture and preventing the pallet 4 from tilting or shifting due to equipment vibration or external force.

[0024] When the equipment needs to be stored after shutdown, first place the screw 9 in the resting position of the sliding hole of the swing arm 7, then lift the tray 4 upwards. Then, the operator can overcome the elastic tension of the tension spring 12 and push the fixing rod 11 to drive the swing arm 7 to rotate around the axis of the support 6 away from the protective plate 2. After the groove 14 is aligned with the positioning rod 8, fold and retract the tray 4 until the tray 4 fits against the side wall of the leveling machine 1, reducing the space occupied when the equipment is idle and achieving convenient storage.

[0025] This utility model integrates material support and limiting / guiding functions by setting a foldable and retractable tray 4 on one side of the leveling machine 1. The tray 4 forms a horizontal and stable support platform with the precise cooperation of the positioning rod 8 at the end of the swing arm 7 and its own positioning groove 5, providing a lower reference support for the die-cut printed materials, avoiding material sagging, displacement or friction damage, and ensuring that it enters the heating roller leveling area smoothly to improve leveling accuracy. When the machine is idle, the tray 4 can be folded and attached to the side wall of the leveling machine 1 along the cooperation trajectory of the positioning rod 8 and the positioning groove 5 without disassembly, by rotating the swing arm 7. This greatly reduces the space occupation rate, and the structure is simple and easy to operate. It improves the overall performance of the equipment while effectively controlling the equipment investment cost.
